The tips ofthe 35 ticular .and novelshape, in that they are a plan view of an yaeroplane embodying the upper planes are on a straight line with the invention.

This body-portion 10 is provided 10, and thereby the planes 24 and 25 are at'its rear with a rudder 15, controlled by inclined v1n 'one or the other direction in respect to the horizontal, and thereby the guiding rods 16 and 17, and at the front of the body 10 is a propeller 18..

The planes 20, 21, 22 and 23 are of a paredge tapered oli at its ends, which is clearly 90 indicated at 10, 42, 43, in Fig. 1, and this form of rudder enables very easy entrance and passage of the rudder through4 the' air. he motorand all necessary operating and curved from their uppermost point indicated, for instance', by 29, downwardly to-A ward the body l0, and are-also curved .to-

ward the tip 30 of 'the plane.' They are also .curved convexly forward of a straight line betweenthe tips, as seen in Fig. 1. The inner end of each plane is lower than the tip, as'seen in Fig. 3. The u per plane is located forward of the lower p ne"7 as-seen'in Figs. `5. 1-.and2- The curvatureof the plane brings about-the advantage that the dropping of the aeroplane is impeded, in' that by thls curving a certain amount .of airis gathered by the inclined surfaces of the-plane, and

3 underneath the plane. From the 'extreme forward points 31 of the planes, the planes arel curved rearwardly, las indicated y 32, to the tip 30, and from the point'Bll-to'the innermost points 33. A similar curvatureexists at the rear edgeof the plane, where the'curvatur'e commences at the central point controlling devices are contained within the ,95

body 10j The propeller blades have their inner por-V tions 'approximately in line with the tips, as v indicated by ldotted line 52 in Figs. 1 and 2,

'25", so as to present an inclined plane tothe' air. This enables a very smooth. andlrapid i movement of the propeller in the air,lan'd` the propulsion of the aeroplane by the rota tion of 'the propeller.v 'By my improved 105 planes' and propellers, a very improved de vice is produced.

The three essential4 features are the'loca=' .tion anddouble curvature or inclination of cir shape,jand the position ofthe' pro#` peller, and its shape. A i, 5

a boat hull has to be provided yin place ot' the body 10, and the rudder 15 acts as. a rudder to the boat.

One embodiment of the invention has been shown and described. It is obvious, however, that changes may be madeV therein Without departing troni the spirit of the invention as set forth in t-lie claims.
